I'm not sure of the status of the project now. I will try to find out. As far as I recall, the main thing was that there was a large database of 'known' cases for the statistics to work on, which at the time put it 'ahead of the competition'. I think the system depends on having this database. I hazily recall that they are now working on Macs, though I am really out of my depth here.
